For the purpose of explanation, the following illustrations display all 
warning lights and indicators illuminated.
The units used on the meters and some indicators may differ depending on 
the target region.
Warning lights inform the driver 
of malfunctions in the indicated 
vehicle’s systems.
Warning lights and indicators
The warning lights and indicators on the instrument cluster, 
overhead console panel and outside rear view mirrors inform 
the driver of the status of the vehicle’s various systems.

The multi-information display 
can be switched between dis-
play and hidden. Switches the items of the odom-
eter, trip meter A, trip meter B 
and   (oil maintenance) by 
pressing the “ODO TRIP” 
switch.
When the trip meter is dis-
played, pressing and holding the 
switch will reset the trip meter.
■Pop-up display
Distance until the next engine oil 
change will be displayed when a 
warning message indicating that 
oil maintenance is required or 
should be performed soon is 
displayed.
WARNING
■The information display at 
low temperatures
Allow the interior of the vehicle to 
warm up before using the liquid 
crystal information display. At 
extremely low temperatures, the 
display monitor may respond 
slowly, and display changes may 
be delayed.
NOTICE
■To prevent damage to the 
engine and its components
The engine may be overheating if 
“Engine Coolant Temp High Stop 
in a Safe Place See Owner’s 
Manual” is shown on the multi-
information display. In this case, 
immediately stop the vehicle in a 
safe place, and check the engine 
after it has cooled completely.

4366-1. Using the air conditioning system and defogger
switch.
■Defogging the rear window 
(if equipped)
A defogger is used to defog the 
rear window.
Press the rear window defogger 
switch.
When the rear window defogger 
switch is on, the indicator illumi-
nates on the rear window defogger 
switch.
The defogger will automatically turn 
off after 15 minutes.
■Defogging the rear window 
and outside rear view mir-
rors (if equipped)
Defoggers are used to defog the 
rear window and to remove rain-
drops, dew and frost from the 
outside rear view mirrors.
Press the rear window and out-
side rear view mirror defoggers 
switch.
When the rear window and outside 
rear view mirror defoggers switch is 
on, the indicator illuminates on the 
rear window and outside rear view 
mirror defoggers switch.
The defoggers will automatically 
turn off after 15 minutes.
■When the outside temperature 
exceeds 75°F (24°C) and the air 
conditioning system is on
●In order to reduce the air condi-
tioning power consumption, the air 
conditioning system may switch to 
recirculated air mode automati-
cally.
This may also reduce fuel con-
sumption.
●Recirculated air mode is selected 
as a default mode when the power 
switch is turned to ON.
●It is possible to switch to outside 
air mode at any time by pressing 
the outside air mode switch.
■Heating
●In HV mode, the gasoline engine 
may operate in order to extract 
heat from the engine coolant via 
the heater.
●In EV mode, heating is done by a 
heat pump system.
• When the outside temperature is  low or it is snowing, compared to 
conventional vehicles, heating 
may be less effective and warm 
air may not come out.
• When the outside heat exchanger 
is frosted over, fan speed declines 
and it may become harder to heat 
the interior. However, it is not a 
malfunction. In this situation, the 
air temperature from the outlets 
may not change even though the 
set temperature is raised.
• When “AUTO” switch is turned on,  the heating is controlled opti-
mally. Therefore, the set heating 
performance may not be achieved 
even if the fan speed setting is 
increased.
Outside heat exchanger
●In the following situations the gas-
oline engine may operate in order 
to extract heat from the engine 
coolant via the heater even in EV 
mode.
• The outside temperature is  approximately 75°F (24°C) or low
• Windshield defogger is operating

WARNING
The engine compartment contains 
many mechanisms and fluids that 
may move suddenly, become hot, 
or become electrically energized. 
To avoid death or serious injury, 
observe the following precautions.
■When working on the engine 
compartment
●Make sure that “POWER ON” 
on the meter and the “READY” 
indicator are both off.
●Keep hands, clothing and tools 
away from the moving fan.
●Be careful not to touch the 
engine, power control unit, radi-
ator, exhaust manifold, etc. right 
after driving as they may be hot. 
Oil and other fluids may also be 
hot.
●Do not leave anything that may 
burn easily, such as paper and 
rags, in the engine compart-
ment.
ItemsParts and tools●Do not smoke, cause sparks or 
expose an open flame to fuel or 
the battery. Fuel and battery 
fumes are flammable.
■When working near the elec-
tric cooling fan or radiator 
grille
Be sure the power switch is OFF.
With the power switch in ON, the 
electric cooling fan may automati-
cally start to run if the air condi-
tioning is on and/or the coolant 
temperature is high. ( P.508)
■Safety glasses
Wear safety glasses to prevent 
flying or falling material, fluid 
spray, etc., from getting in your 
eyes.
NOTICE
■If you remove the air cleaner 
filter
Driving with the air cleaner filter 
removed may cause excessive 
engine wear due to dirt in the air.

Maintenance and care
■Checking fluid level
The brake fluid level should be 
between the “MAX” and “MIN” 
lines on the tank.
■Adding fluid
1 Slide and lift up the rubber 
strip to partly remove it, and  then remove the clip remove 
it as shown in the illustration.
2 Disconnect the claws and 
remove the service cover.
3 Remove the reservoir cap.
4 Add brake fluid slowly while 
checking the fluid level.
Make sure to check the fluid 
type and prepare the necessary 
WARNING
■When the electric cooling fan 
is operating
Do not touch the engine compart-
ment.
With the power switch in ON, the 
electric cooling fan may automati-
cally start to run if the air condi-
tioning is on and/or the coolant 
temperature is high. Be sure the 
power switch is OFF when work-
ing near the electric cooling fan or 
radiator grille.
